ASTM E10 Determining the Brinell hardness of Metallic Materials

Scope:

ASTM E10 test is useful in providing information about the physical properties of metallic materials such as tensile strength, ductility, and wear resistance. This is also significant in quality control and the selection of materials. This test method is also useful for acceptance testing in the commercial shipping industry.

Procedure:

In ASTM E10, the Brinell test is carried out by bringing the indenter into contact with the test surface. Then the test force F is applied and maintained for about 10s to 15s. Once the dwell time is achieved, the applied force is removed without vibration. Brinell hardness number is calculated by taking the arithmetic mean of the measurements of the indentation diameter.

Specimen size:

Ambient temperature should be within the limits of 10 to 35 °C (50 to 95 °F).

Data

As per ASTM E10, the Brinell hardness number is calculated as:

 Where:

F _kgf = test force in kgf,

D = diameter of the indenter ball in mm, and

d = measured mean diameter of the indentation in mm

Conclusion:

ASTM E10 test is useful in providing information about the physical properties of metallic materials such as tensile strength, ductility, and wear resistance.
